I was watching a YouTube video the other day and I found a sentence that intrigued me. The woman, Jessica Vill, was talking about her wig collection and when describing one of the wigs she said
There's no shine whatsoever to it, um, and, it's so much more thicker.
Obviously, she should have used a regular form of the adjective in that case ('more thick') so the sentence seems incorrect. The woman in the video is a native speaker of English from the United States and grew up in Florida. Additionally, this is not the first time that I heard a native speaker of English use the word 'more' with a comparative form of the adjective, which brings me to my question:
Is it correct to use 'more' in combination with comparative adjectives?
Also, I am wondering if some of you have ever heard a similar sentence before? Is such a structure being frequently used among speakers of English?
